During the Activity

Draw several triangles, compare them, and look for any similarities among all the triangles

Draw several different sized equilateral triangles, compare the triangles, and look for similarities

Do the same experiment with rectangles, and then squares

Note, the rectangles come in all shapes; the squares are all the same shape but different sizes

Give students the picture of several different-sized squares, and have them measure the length of the diagonal and the perimeter of each square, record their findings on the recording sheet, and look for patterns

Record the same data for other regular polygons of several different sizes and look for patterns
